The GCW/FMI SWE Tracker is a product of the Finnish Meteorological Institute (FMI), based on GlobSnow snow water equivalent (SWE). It was developed as part of the GCW Snow Watch project and illustrates the current Northern Hemisphere snow water equivalent relative to the long-term mean and variability (figure 3), The Nature study is entitled "Patterns and trends of Northern Hemisphere snow mass from 1980 to 2018" authored by: Pulliainen, Jouni; Luojus, Kari; Derksen, Chris; Mudryk, Lawrence; Lemmetyinen, Juha; Salminen, Miia; Ikonen, Jaakko; Takala, Matias; Cohen, Juval; Smolander, Tuomo; Norberg, Johannes and published in the Journal Nature, The study is available here, © 2020 World Meteorological Organization (WMO), Northern Hemisphere snow can now be reliably estimated, study published in the scientific journal Nature, UN chief: this is a moment of truth for people and planet. The results show that the amount of rainfall has increased in the northern regions, especially in the northern parts of Asia,” Jouni Pulliainen said. 2020 Northern Hemisphere Total Snow Mass Increases to 300 Gigatons Above Avg Data from the Finnish Meteorological Institute (FMI) reveals that the “Total Snow Mass for the Northern Hemisphere” has been consistently above the 30 year average over the past few years, and now, 2020 is actually INCREASING that rate of growth. The amount of snow this winter is shown in red, the most recent observation is from 13 May 2020. Following on from one of its snowiest winters on record in 2019-2 0 comes the first 2020-21 data-points from the Finnish Meteorological Institute (FMI). In northern areas, where rainfall generally turns to snow in winter, the snow mass has remained the same or even increased. – Jouni Pulliainen, of the Finnish Meteorological Institute. What they clearly reveal is that the Northern Hemisphere is at it again, continuing the trend of growth observed in recent years. For the first time, snow researchers from the Finnish Meteorological Institute in collaboration with Environment and Climate Change Canada have reliably estimated the amount and the trend in the seasonal snow of the Northern Hemisphere between 1980 and 2018. The study originated in the context of the multi-year collaboration of the snow researchers involved in Snow Watch activities of WMO’s Global Cryosphere Watch project. German broadcaster RTL here reported how Northern Hemisphere snow mass has reached the highest level in years. Those living in higher latitudes in the Northern Hemisphere should be concerned when the snow begins to accumulate causing the glaciers to expands.

This year’s Northern Hemisphere snowfall data, collated by the Finnish Meteorological Institute (FMI) reveals that the 2019/2020 season has become one of the snowiest NH Winters on record, joining the uptick witnessed over the past few years. The research for this publication originated and was partially conducted in the context of the Satellite Snow Product Intercomparison and Evaluation Exercise (SnowPEx) project. They found that snow mass between 1980 and 2018 has remained the same in Eurasia and decreased in North America, but the extent of cover has decreased. Finnish Meteorological Institute, modified from the chart presented in the Nature article, This past winter the snow line has been hundreds, in some places even thousands of kilometres north of normal. Data from the Finnish Meteorological Institute (FMI) reveals that the “Total Snow Mass for the Northern Hemisphere” has been consistently above the 30 year average over the past few years, and now, 2020 is actually INCREASING that rate of growth. The Finnish Meteorological Institute (FMI) reports the total amount of snow in the northern hemisphere this winter season has been well above the long-term average from 1982 to 2012. Researchers from the Finnish Meteorological Institute have reliably estimated the amount of snow in the Northern Hemisphere. We've published the most accurate reconstruction of Northern Hemisphere snow mass for the passive microwave satellite-era (1980-2018), up to date.

Snow mass in the Northern Hemisphere in gigatonnes. In the early winter, there were numerous large snowstorms that brought a large amount of snow to the area with each storm. The amount of snow cover and its changes affect the climate system (including the carbon cycle) and freshwater resources. Credit: Nature. HI-RES GIF [1.45 MB] Thank you for liking. Observations. It is only through its effect on precession and obliquity that eccentricity becomes relevant. The analysis illustrated the important contributions from both remote sensing and land surface modelling communities. March’s annual snow mass and its trend. Data from the Finnish Meteorological Institute (FMI) reveals that the Total Snow Mass for the Northern Hemisphere has been consistently above the 30 year average for the majority of the season, and is now actually increasing its rate of growth. But the 2020 fall extent is likely to surpass that of any previous year, based on data from the Finnish Meteorological Institute for Northern Hemisphere snow mass (as opposed to extent) to date. More information at our Data Privacy Policy, "Not here to worship what is known, but to question it" - Jacob Bronowski. The Northern Hemisphere’s total snow mass, aided by central Asia’s record snowfall, is now sitting above the 1982-2012 average by 400 gigatons (as of Nov 21). Finnish Meteorological Institute and WMO Global Cryosphere Watch. “The method can be used to combine different observations and it provides more accurate information about the amount of snow than ever before. In long time series one can observe, that the total snow mass in the northern hemisphere is on average less in the spring and melting is starting earlier.
